LADLE.

Application filed June 27,

. To all whom, it may concern.-

Be it known that I, .MUNSON H. TREAD- WELL, a citizen of the United States, residing at. NewYork, in the county of New York and State of New York, have invented certain new and useful Improvements in Ladles, of which the following is a full, clear, and exact specification. 4

This invention relates to ladles, and more particularly to slag ladles for use in connec filgn. with blast furnaces, foundries and the The object of the invention is to provided a ladle in which the liability to breakage, due

tounequal expansion, is reduced to a minimum, and in which should breakage occur, notwithstanding precautions taken to prevent the same, the broken part may be easily replaced, without necessarily interfering with the continued use of the other parts.

In ."carrying out my invention, I provide means whereby that portion of the ladle which is especially subject to breakage by.

The upper edge has a grooved, circumferential flange 2, within which the lower side of the intermediate annularsection 3 fits.

The inner diameter of the annular lntermediate section 3 is slightly larger than that of the bottom section, so as to form a shoulder 6, and the function of this shoulder is to permit the slag or cinder to be freely dis- Specification of Letters Patent.

charged from the ladle, when cooled, by preventing the. mass from flowing in between the sections and adhering thereto. The intermediate section carries a number of pairs of lugs 8, to which a ring 9, carrying trunnions 10, is fastened, so as to permit the'ladle to be mounted on a truck, In smaller portable sizes, instead of trunnions, long handles may be used. The intermediate sections may be channeled at the top, similarly to the bottom section if desired, and the next section made to fit therein, or lugs may also be used for this purpose. While the-drawings show but one intermediate section, it will be obvious that more than one may be from the invention.

has a flange 13, with radial slots 14 therein, and the segments 15,.forming the topsection, have flanges l6, withslots 17 therein at right angles to the slots 14, and through these slots pass bolts 1.8 which-are set firmly to hold the segments 15 in engagement with the upper edge of the intermediate section. By providing these slots at right angles, the assembly of the parts is facilitated, and also the substitution of a new art for a damaged one. It will also benote that the segments are of larger diameter than the intermediate or bottom section, so as to prevent lodgment of the liquid or solidified material. The segments 15 carry lugs 20, through which bolts 21 ass to loosely secure the segments totract with changes in temperature. The

may be filled with fire clay, in order to prevent leakage of molten material.

26 re resents a truck, which may be of any desirabie construction, and carrying supports to receive the trunnions 10, thereby permitting the ladle to be tipped to discharge, the contents. It will be understood,

to this class of ladles, as my improvements are also applicable to so-called stopper ladles, etc. diate and bottom sections may be made in one lpiece, and the expansible top secured direct y thereto, as shown in Fig. 7.

As applied to huge ladles, of a ton or more ca acity, my invention efiects a *onsiderabi e economy in maintenance. L otwithstanding the various kinds of linings which have been proposed for slag ladles, they are space 23 formed between the sections 1 and 3 however, that I do not restrict the invention used in the same manner, without departing The upper side of the intermediate section get er, so that they can expand and con For some" ladles, the intermevery important cause of deterioration is that when the ladles are in use they are not often filled to the top, on accountof the variance of the slag supply. In a caseof this, kind, the .lower portion of a bowl made in one piece will expand irf the lower part, putting such a strain upon the upperortion as to also a fact, that-the to cause the same to fracture or reak.-- It is of the slag, even when the pot has been ed com letely, will cool off before'the main body.' t can read-' ily be seen that this operation will have the same effect-u on the pot, as when it is not completely. ed.-; "By providin an expansi'ble rim, as before descri'bed",ia danger of fracturing theftopof; the -.ladl e is avoided,
